Sql query with dynamic fiscal year

Question

Hi,
I wrote this query with static fiscal year and fiscal period, I need info on making the variables dynamic
Fiscal year : starts from July1st. So this year until June'30 it is '2011' and from July'1st its '2012'
Fiscal period: July1st its '1' and June'1st its '12'
Query:
select distinct o.c_num, o.ac_num, s.sub_ac_num, o.fiscal_year, o.ac_exp_date, s.sub_ac_ind
                         from org_account o
                              left outer join sub_account s
                              on o.c_num = s.c_num and o.ac_num = s.ac_num
                         where (o.ac_exp_date >= CURRENT_DATE or o.ac_exp_date is null)
                         and o.fiscal_year = *'2011'* --> need to be dynamic
                         and o.fiscal_period = *'12'* --> need to be dynamic
thanks,
Mano

Hi, Mano,
Welcome to the forum!
Whenever you have a question, please post a little sample data (CREATE TABLE and INSERT statements), and the results you want from that data.
Always say which version of Oracle you're using.
Since this is your first thread, I'll post some sample data for you:
CREATE TABLE     table_x
(     dt     DATE
INSERT INTO table_x (dt) VALUES (DATE '2010-12-31');
INSERT INTO table_x (dt) VALUES (DATE '2011-01-01');
INSERT INTO table_x (dt) VALUES (DATE '2011-06-02');
INSERT INTO table_x (dt) VALUES (DATE '2011-06-30');
INSERT INTO table_x (dt) VALUES (DATE '2011-07-01');Is this the output you would want from that data?
DT          FISCAL_YEAR     FISCAL_PERIOD
31-Dec-2010 2011            06
01-Jan-2011 2011            07
02-Jun-2011 2011            12
30-Jun-2011 2011            12
01-Jul-2011 2012            01If so, here's one way to get it:
SELECT       dt
,       TO_CHAR ( ADD_MONTHS (dt, 6)
            , 'YYYY'
            )     AS fiscal_year
,       TO_CHAR ( ADD_MONTHS (dt, 6)
            , 'MM'
            )     AS fiscal_period
FROM       table_x
ORDER BY  dt
;Since your fiscal year starts 6 months before the calendar year, you need to add 6 months to the actual date to get the fiscal year and month.
The query above produces strings for fiscal_year and fiscal_period. If you'd rather have NUMBERs, then use EXTRACT instead of TO_CHAR:
SELECT       dt
,       EXTRACT (      YEAR
            FROM     ADD_MONTHS (dt, 6)
            )     AS fiscal_year
,       EXTRACT (      MONTH
            FROM     ADD_MONTHS (dt, 6)
            )     AS fiscal_period
FROM       table_x
ORDER BY  dt
;The first query will work in Oracle 6 (and higher).
I'm not sure when EXTRACT was introduced. It definitely works in Oracle 10, and may be available in earlier versions, too.
